Internet Access Features Shared Internet Access. All users on the LAN or WLAN can access the Internet through the ADE-4300/ADW-4300, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation). Built-in ADSL 2/2+ Modem. The ADE-4300/ADW-4300 has a built-in ADSL 2/2+ modem, supporting all common ADSL 2/2+ connections. 1

7 ADE-4300/ADW-4300 User Guide IPoA, PPPoE, PPPoA, Direct Connection Support. The ADE-4300/ADW supports all common connection methods. Auto-detection of Internet Connection Method. In most situations, the ADE-4300/ADW-4300 can test your ADSL and Internet connection to determine the connection method used by your ISP. Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the ADE-4300/ADW-4300 supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. Advanced Internet Functions Application Level Gateways (ALGs). Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally. Special Applications. This feature, also called Port Triggering, allows you to use Internet applications which normally do not function when used behind a firewall. Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog Server. Log data can also be ed to you. Access Control. Allows administrators to restrict the Internet Access available to PCs on your LAN. Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall Rules to determine which incoming and outgoing traffic should be permitted. Universal Plug and Play (UPnP) UPnP allows automatic discovery and configuration of the Broadband Router. UPnP is supported by Windows ME, XP, or later. Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows users to connect to Servers on your LAN using a Domain Name, even if you have a dynamic IP address which changes every time you connect. Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at certain times. This provides great flexibility in controlling Internet -bound traffic. VPN Connectivity. Supports up to 8 IPSec VPN with DES, 3DES encryption and SHA-1 / MD5 authentication, the network traffic over public Internet is secured. PPTP Server. The ADE-4300/ADW-4300 emulates a Microsoft PPTP VPN Server, allowing clients to use the Microsoft VPN client provided in Windows. VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. Wireless Features (ADW-4300 only) Standards Compliant. The ADW-4300 complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. 2

8 Introduction Supports both b and g Wireless Stations. The g standard provides for backward compatibility with the b standard, so both b and g Wireless stations can be used simultaneously. Speeds to 54Mbps. All speeds up to the g maximum of 54Mbps are supported. WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing protection against snoopers. WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission, providing protection against snoopers. The WPA-PSK is a later standard than WEP, and provides both easier configuration and greater security than WEP. Wireless MAC Access Control. The Wireless Access Control feature can check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN. Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. LAN Features 4-Port Switching Hub. The ADE-4300/ADW-4300 incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The ADE- 4300/ADW-4300 can act as a DHCP Server for devices on your local LAN and WLAN. Configuration & Management Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration. Configuration File Upload/Download. Save (download) the configuration data from the ADE-4300/ADW-4300 to your PC, and restore (upload) a previously-saved configuration file to the ADE-4300/ADW Remote Management. The ADE-4300/ADW-4300 can be managed from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet. Network Diagnostics. You can use the ADE-4300/ADW-4300 to perform a Ping or DNS lookup. Security Features Password - protected Configuration. Password protection is provided to prevent unauthorized users from modifying the configuration data and settings. Wireless LAN Security. (ADW-4300 only) WPA-PSK, WEP and Wireless access control by MAC address are all supported. The MAC-level access control feature can be used to prevent unknown wireless stations from accessing your LAN. NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the ADE-4300/ADW

9 ADE-4300/ADW-4300 User Guide Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. The ADE-4300/ADW-4300 incorporates protection against DoS attacks. 4

20 Setup Home Screen After finishing the Setup Wizard, you will see the Home screen. When you connect in future, you will see this screen when you connect. An example screen is shown below. Main Menu Figure 7: Home Screen The main menu, on the left, contains links to the most-commonly used screen. To see the links to the other available screens, click "Advanced" or "Administration". The main menu also contains two (2) buttons: Log Out - When finished, you should click this button to logout. Restart - Use this if you wish to restart the ADE-4300/ADW Note that restarting the Router will break any existing connections to or through the Router. Navigation & Data Input Use the menu bar on the left of the screen, and the "Back" button on your Browser, for navigation. Changing to another screen without clicking "Save" does NOT save any changes you may have made. You must "Save" before changing screens or your data will be ignored. On each screen, clicking the "Help" button will display help for that screen. 15

21 ADE-4300/ADW-4300 User Guide LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below. Data - LAN Screen TCP/IP IP Address Subnet Mask Figure 8: LAN Screen IP address for the ADE-4300/ADW-4300, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. The default value is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the ADE-4300/ADW-4300 is attached (the same value as the PCs on that LAN segment). DHCP Server If Enabled, the ADE-4300/ADW-4300 will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be reconfigured to treat the ADE-4300/ADW-4300 as the default Gateway. See the following section for further details. The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP. DHCP What DHCP Does A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request. The client request is made when the client device starts up (boots). 16

22 Setup The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address. The ADE-4300/ADW-4300 can act as a DHCP server. Windows 95/98/ME and other non-server versions of Windows will act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client". You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.) Using the ADE-4300/ADW-4300's DHCP Server This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can: Enable or Disable the ADE-4300/ADW-4300's DHCP Server function. Set the range of IP Addresses allocated to PCs by the DHCP Server function. You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server. Using another DHCP Server You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the ADE-4300/ADW-4300's, the following procedure is required. Disable the DHCP Server feature in the ADE-4300/ADW This setting is on the LAN screen. Configure the DHCP Server to provide the ADE-4300/ADW-4300's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP for all non-server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings. 17

23 ADE-4300/ADW-4300 User Guide Wireless Screen (ADW-4300 only) The ADW-4300's settings must match the other Wireless stations. Note that the ADW-4300 will automatically accept both b and g connections, and no configuration is required for this feature. To change the ADW-4300's default settings for the Wireless Access Point feature, use the Wireless link on the main menu to reach the Wireless screen. An example screen is shown below. Data - Wireless Screen Identification Figure 9: Wireless Screen Region Station name SSID Select the correct domain for your location. It is your responsibility to ensure: That the ADW-4300 is only used in domains for which is licensed. That you select the correct domain, so that only the legal channels for that domain can be selected. This is the same as the "Device Name" for the ADW This is also called the "Network Name". If using an ESS (Extended Service Set, with multiple access points) this ID is called an ESSID (Extended Service Set Identifier). To communicate, all Wireless stations should use the same SSID/ESSID. 18

24 Setup Options Mode Channel No. Broadcast SSID Wireless Security Current Setting Configure Button Access Point Enable Wireless Access Point Select the desired mode: G-plus (TI) This allows clients to use any of the following modes: Standard b B+ (Texas Instruments proprietary enhanced mode) Standard g G-plus (Texas Instruments proprietary enhanced mode). This mode can increase throughput by up to 50%, but will only work between compatible TI wireless stations g & b - Both g and b Wireless stations will be able to use the ADW g only - Only g Wireless stations can use the ADW b only - Only b connections are available g Wireless Stations will only be able to use the ADW if they are fully backward-compatible with the b standard. Select the Channel you wish to use on your Wireless LAN. If you experience interference (shown by lost connections and/or slow data transfers) you may need to experiment with different channels to see which is the best. If using multiple Access Points, adjacent Access Points should use different Channels to reduce interference. If enabled, the ADW-4300 will broadcast its SSID. This allows PCs and other wireless stations to detect this Access Point and use the correct SSID. If disabled, PC users will have to manually enter the SSID and other details of the wireless interface before they can connect to this Access Point. The current Wireless security is displayed. The default value is Disabled. Click this button to access the Wireless security sub-screen, and view or change the settings. See the following section for details. Enable this if you want to use Wireless Access Point function. If disabled, no Wireless stations can use the Access Point function, and all connections must be made via the wired LAN. 19

25 ADE-4300/ADW-4300 User Guide Allow access by Set Stations Button Use this feature to determine which Wireless stations can use the Access Point. The options are: All Wireless Stations - All wireless stations can use the access point, provided they have the correct SSID and security settings. Trusted Wireless stations only - Only wireless stations you designate as "Trusted" can use the Access Point, even if they have the correct SSID and security settings. This feature uses the MAC address to identify Wireless stations. The MAC address is a low-level network identifier which is unique to each PC or network device. To define the trusted wireless stations, use the "Set Stations" button. Click this button to manage the trusted PC database. 20

26 Setup Wireless Security (ADW-4300 only) This screen is accessed by clicking the "Configure" button on the Wireless screen. There are 3 options for Wireless security: Disabled - no data encryption is used. WEP - data is encrypted using the WEP standard. WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP. WEP Wireless Security Data - WEP Screen WEP Data Encryption Figure 10: WEP WEP Data Encryption Authentication Type Default Key Select the desired option, and ensure the Wireless Stations use the same setting. 64 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 64 Bit Encryption, the key size is 10 chars in HEX (0~9 and A~F). 128 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 128 Bit Encryption, the key size is 26 chars in HEX (0~9 and A~F). Normally, this should be left at the default value of "Automatic". If changed to "Open System" or "Shared Key", ensure that your Wireless Stations use the same setting. Select the key you wish to be the default. Transmitted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only. 21

27 ADE-4300/ADW-4300 User Guide You must enter a Key Value for the Default Key. Key Value Passphrase Enter the key value or values you wish to use. The Default Key is required, the other keys are optional. Other stations must have the same key. If desired, you can generate a key from a phrase, instead of entering the key value directly.

31 ADE-4300/ADW-4300 User Guide Mode Screen Use this screen to change the mode between Router mode and Modem (Bridge) mode. Select the desired option, and click "Save". Figure 15: Mode Screen Router Modem Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related information to all Wireless (ADW-4300 only) and LAN users. Only the ADSL Modem component is operational. All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point (ADW- 4300). All traffic received on either the Wireless (ADW-4300) or LAN interface will be sent over the ADSL connection. Notes: Generally, you should NOT use modem mode. Only select this mode if you are sure this is what you want. After changing the mode, this device will restart, which will take a few seconds. The menu will also change, depending on the mode you are in. The Wireless Access Point (ADW-4300 only) can function in either Router or Modem mode. But generally it is not a good idea to combine a Modem with an Access Point, because all data received from the wireless stations will be sent over the modem connection. (Since the modem is transparent, it does not examine the traffic to determine whether the traffic is for the LAN or the WAN.) For details on using Modem Mode, see Chapter 8. 26

32 Chapter 4 PC Configuration 4 This Chapter details the PC Configuration required on the local ("Internal") LAN. Overview For each PC, the following may need to be configured: TCP/IP network settings Internet Access configuration Wireless configuration (ADW-4300 only) Windows Clients This section describes how to configure Windows clients for Internet access via the ADE-4300/ADW The first step is to check the PC's TCP/IP settings. The ADE-4300/ADW-4300 uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP protocol be installed and configured on each PC. TCP/IP Settings - Overview If using the default ADE-4300/ADW-4300 s settings, and the default Windows TCP/IP settings, no changes need to be made. By default, the ADE-4300/ADW-4300 will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots. For all non-server versions of Windows, the default TCP/IP setting is to act as a DHCP client. If using a Fixed (specified) IP address, the following changes are required: The Gateway must be set to the IP address of the ADE-4300/ADW-4300 The DNS should be set to the address provided by your ISP. If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 8 - Advanced Setup for details. 27

69 ADE-4300/ADW-4300 User Guide Dynamic DNS (Domain Name Server) This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you. DDNS Services work as follows: 1. You must register for the service at one of the listed DDNS Service providers. 2. After registration, use the Service provider's normal procedure to obtain your desired Domain name. 3. Enter your DDNS data on the ADE-4300/ADW-4300's DDNS screen, and enable the DDNS feature. 4. The ADE-4300/ADW-4300 will then automatically ensure that your current IP Address is recorded at the DDNS service provider's Domain Name Server. 5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen. Dynamic DNS Screen Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following: Data - Dynamic DNS Screen DDNS Service Use a Dynamic DNS Service Service Provider Web Site Figure 52: DDNS Screen Use this to enable or disable the DDNS feature as required.

If this setting is not enabled, the default NTP Servers are used. This displays the current time on the ADE-4300/ADW-4300, at the time the page is loaded. 75

81 ADE-4300/ADW-4300 User Guide Virtual Servers This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: Your Server does not have a valid external IP Address. Attempts to connect to devices on your LAN are blocked by the firewall in this device. The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below. Figure 60: Virtual Servers IP Address seen by Internet Users Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols. To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address. Virtual Servers Screen The "Virtual Servers" feature allows Internet Users to access PCs on your LAN. The PCs must be running the appropriate Server Software. For Internet Users, ALL of your Servers have the same IP address. This IP address is allocated by your ISP. To make it easier for Internet users to connect to your Servers, you can use the "DDNS" feature. This allows Internet users to connect to your Servers with a URL, rather than an IP address. This technology works even if your ISP allocates dy- 76

82 Advanced Features namic IP addresses (IP address is allocated upon connection, so it may change each time you connect). Data - Virtual Servers Screen Servers Servers Properties Enable PC (Server) Figure 61: Virtual Servers Screen This lists a number of common Server types. If the desired Server type is not listed, you can create a Firewall Rule to achieve the same effect as the Virtual Server function. Use this to Enable or Disable support for this Server, as required. If Enabled, you must select the PC to which this traffic will be sent. Select the PC for this Server. The PC must be running the appropriate Server software. For each entry, the PC must be running the appropriate Server software. If the desired Server type is not listed, you can define your own Servers, using the Firewall Rules. Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g. ftp:// It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Servers using a URL, rather than an IP Address. From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP 77

83 ADE-4300/ADW-4300 User Guide VPN (IPSec) The VPN (Virtual Private Network) feature in the ADE-4300/ADW-4300 allows you to create a VPN connection between 2 ADE-4300/ADW-4300s, or a remote PC to establish a VPN connection to the ADE-4300/ADW To establish a VPN connection from a remote PC to the ADE-4300/ADW-4300, you need suitable (IPSec) VPN client software on your PC. For more information about VPNs, please refer to Appendix C - About VPNs. VPN Policies A "VPN Policy" contains all the configuration data for a particular VPN connection. Generally, you will have to create one policy for each site you wish to connect to. The remote VPN Gateway (or client) needs to have matching configuration. Traffic covered by an enabled policy will automatically be sent via a VPN tunnel. If the VPN tunnel does not exist, it will be created. The VPN tunnel is created according to the parameters in the SA (Security Association). The remote VPN Endpoint must have a matching SA, or it will refuse the connection. There are 2 types of VPN Policies: Manual - All settings (including the keys) for the VPN tunnel are manually input at each end (both VPN Endpoints). Auto - Some parameters for the VPN tunnel are generated automatically. This requires using the IKE (Internet Key Exchange) protocol to perform negotiations between the 2 VPN Endpoints. 78

84 Advanced Features VPN Policies Screen This screen is displayed when you select VPN on the Advanced menu. It allows you to create, modify and manage your VPN Policies. If you have not created any policies, the Policy Table will be empty.

Click "Save" after making any changes. Name - Each policy is given a unique name to identify it. This name is not known to the remote VPN endpoint; it is used only to assist managing your policies. Endpoint - The address of the remote VPN endpoint. Type - The Type is "Auto" or "Manual" as explained above. Local LAN - IP address or subnet on your local LAN. Traffic must be from (or to) these addresses to be covered by this policy. Remote LAN - IP address or subnet on the remote LAN. Traffic must be to (or from) these addresses to be covered by this policy. ESP - ESP (Encapsulating Security Payload) encryption protocol used for the VPN data. Save any changes to the "Enable" setting for each policy. Edit (modify) the selected policy. (Select a policy by clicking on the radio button.) Delete the selected policy. (Select a policy by clicking on the radio button.) Change to the input screen for an "Auto" policy. See the following section for details. When the new policy is saved, it will appear in the bottom row of the Policy Table. Change to the input screen for an "Manual" policy. See the following section for details.

VPN Auto Policy Screen This screen is displayed when you click the Add Auto Policy button on the VPN Policies screen, or when you edit an existing Auto Policy. It allows you to define or edit an "Auto" VPN policy. An "Auto" VPN policy uses the IKE (Internet Key Protocol) to exchange and negotiate parameters for the IPsec SA (Security Association). Because of this negotiation, it is not necessary for all settings on this VPN Gateway to match the settings on the remote VPN endpoint. Where settings must match, this is indicated. Figure 63: VPN-Auto Policy Screen 80

86 Advanced Features Data - VPN-Auto Policy Screen General Policy Name Remote VPN Endpoint NetBIOS Enable Local LAN Local LAN Remote LAN Remote LAN Enter a unique name to identify this policy. This name is not supplied to the remote VPN endpoint. It is used only to help you manage the policies. If the remote endpoint has a dynamic IP address, select "Dynamic IP address". No "Address Data" input is required. Otherwise, select the desired option (IP address or Domain Name) and enter the address of the remote VPN endpoint you wish to connect to. Note: The remote VPN endpoint must have this VPN Gateway's address entered as its "Remote VPN Endpoint". Check this if you wish NETBIOS traffic to be forwarded over the VPN tunnel. The NETBIOS protocol is used by Microsoft Networking. This identifies which PCs on your LAN are covered by this policy. For each selection, data must be provided as follows: Single address Enter an IP address in the "IP address" field. Typically, this setting is used when you wish to make a single Server on your LAN available to remote users. Subnet address Enter an IP address in the "IP address" field, and the desired network mask in the "Subnet Mask" field. The remote VPN endpoint must have these IP addresses entered as its "Remote" addresses. This identifies which PCs on the remote LAN are covered by this policy. For each selection, data must be provided as follows: Single PC - no subnet Select this option if there is no LAN (only a single PC) at the remote endpoint. If this option is selected, no additional data is required. Single address Enter an IP address in the "IP address" field. This must be an address on the remote LAN. Typically, this setting is used when you wish to access a server on the remote LAN. Subnet address Enter an IP address in the "IP address" field, and the desired network mask in the "Subnet Mask" field.

87 ADE-4300/ADW-4300 User Guide IKE Direction Exchange Mode Diffie-Hellman (DH) Group Local Identity Type Remote Identity Type Remote Identity Data SA Parameters Encryption Authentication Pre-shared Key SA Life Time This setting is used when determining if the IKE policy matches the current traffic. Select the desired option. Responder only - Incoming connections are allowed, but outgoing connections will be blocked. Initiator and Responder - Both incoming and outgoing connections are allowed. IPSec has 2 possibilities - "Main Mode" and "Aggressive Mode". Currently, only "Main Mode" is supported. Ensure the remote VPN endpoint is set to use "Main Mode". The Diffie-Hellman algorithm is used when exchanging keys. The DH Group setting determines the number of bit size used in the exchange. This value must match the value used on the remote VPN Gateway. Select the desired option to match the "Remote Identity Type" setting on the remote VPN endpoint. WAN IP Address - your Internet IP address. Fully Qualified Domain Name - your domain name. Fully Qualified User Name - your name, address, or other ID. Select the desired option to match the "Local Identity Type" setting on the remote VPN endpoint. IP Address - The Internet IP address of the remote VPN endpoint. Fully Qualified Domain Name - the Domain name of the remote VPN endpoint. Fully Qualified User Name - the name, address, or other ID of the remote VPN endpoint. Enter the data for the selection above. (If "IP Address" is selected, no input is required.) Encryption Algorithm used for both IKE and IPSec. This setting must match the setting used on the remote VPN Gateway. Authentication Algorithm used for both IKE and IPSec. This setting must match the setting used on the remote VPN Gateway. The key must be entered both here and on the remote VPN Gateway. This method does not require using a CA (Certificate Authority). This determines the time interval before the SA (Security Association) expires. (It will automatically be re-established if necessary.) While using a short time period (or data amount) increases security, it also degrades performance. It is common to use periods over an hour (3600 seconds) for the SA Life Time. This setting applies to both IKE and IPSec SAs. 82

88 Advanced Features IPSec PFS (Perfect Forward Secrecy) If enabled, security is enhanced by ensuring that the key is changed at regular intervals. Also, even if one key is broken, subsequent keys are no easier to break. (Each key has no relationship to the previous key.) This setting applies to both IKE and IPSec SAs. When configuring the remote endpoint to match this setting, you may have to specify the "Key Group" used. For this device, the "Key Group" is the same as the "DH Group" setting in the IKE section. 83

104 Chapter 7 Advanced Administration 7 This Chapter explains the settings available via the "Administration" section of the menu. Overview Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users. The available settings and features are: PC Database Config File Logging & Diagnostics Remote Admin Routing Upgrade Firmware This is the list of PCs shown when you select the "DMZ PC" or a "Virtual Server". This database is maintained automatically, but you can add and delete entries for PCs which use a Fixed (Static) IP Address. Backup or restore the configuration file for the ADE- 4300/ADW This file contains all the configuration data. View or clear all logs, set ing of log files and alerts. Perform a Ping or DNS Lookup. Allow settings to be changed from the Internet.. Only required if your LAN has other Routers or Gateways. Upgrade the Firmware (software) installed in your ADE- 4300/ADW

105 ADE-4300/ADW-4300 User Guide PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It eliminates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your LAN. However, if you do use a fixed IP address on some devices on your LAN, you should enter details of each such device into the PC database, using the PC Database screen. PC Database Screen An example PC Database screen is shown below. Figure 83: PC Database PCs which are "DHCP Clients" are automatically added to the database, and updated as required. By default, non-server versions of Windows act as "DHCP Clients"; this setting is called "Obtain an IP Address automatically". The ADE-4300/ADW-4300 uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter. This system means you do NOT need to use Fixed (static) IP addresses on your LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC database if required. 100

106 Advanced Features Data - PC Database Screen Known PCs Name IP Address Buttons Add This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". Enter the IP Address of the PC. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. This will add the new PC to the list. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it.

117 ADE-4300/ADW-4300 User Guide Routing Overview If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. If the ADE-4300/ADW-4300 is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. If your LAN has a standard Router (e.g. Cisco) on your LAN, and the ADE- 4300/ADW-4300 is to act as a Gateway for all LAN segments, enable RIP (Routing Information Protocol) and ignore the Static Routing table. If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.) If using Windows 2000 Data center Server as a software Router, enable RIP on the ADE-4300/ADW-4300, and ensure the following Windows 2000 settings are correct: Open Routing and Remote Access In the console tree, select Routing and Remote Access, [server name], IP Routing, RIP In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click "Properties". On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Administration menu. Using this Screen Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously. Static Routing Table If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. The other Routers must also be configured. See Configuring Other Routers on your LAN later in this chapter for further details and an example. 112

118 Advanced Features Figure 90: Routing Screen Data - Routing Screen RIP RIP Direction RIP Version Static Routing Static Routing Table Entries Buttons Add Edit Delete Save Select the desired RIP Direction. Choose the RIP Version for the Server. This list shows all entries in the Routing Table. This area shows details of the selected item in the list. Change any the properties as required, then click the "Edit" button to save the changes to the selected entry. Add a new entry to the Static Routing table, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Update the current Static Routing Table entry, using the data shown in the table area on screen. Delete the current Static Routing Table entry. Save the RIP setting. This has no effect on the Static Routing Table. Configuring Other Routers on your LAN It is essential that all IP packets for devices not on the local LAN be passed to the ADE-4300/ADW-4300, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the ADE- 4300/ADW-4300 as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the ADE- 4300/ADW This router requires that the Default Route is the ADE-4300/ADW- 113

119 ADE-4300/ADW-4300 User Guide 4300 itself. Typically, routers have a special entry for the Default Route. It should be configured as follows. Destination IP Address Network Mask Gateway IP Address Metric 1 Normally , but check your router documentation. Normally , but check your router documentation. The IP Address of the ADE-4300/ADW Other Routers on the Local LAN Other routers on the local LAN must use the ADE-4300/ADW-4300's Local Router as the Default Route. The entries will be the same as the ADE-4300/ADW-4300's local router, with the exception of the Gateway IP Address. For a router with a direct connection to the ADE-4300/ADW-4300's local Router, the Gateway IP Address is the address of the ADE-4300/ADW-4300's local router. For routers which must forward packets to another router before reaching the ADE-4300/ADW-4300's local router, the Gateway IP Address is the address of the intermediate router. Static Routing - Example Figure 91: Routing Example For the ADE-4300/ADW-4300's Routing Table For the LAN shown above, with 2 routers and 3 LAN segments, the ADE-4300/ADW requires 2 entries as follows. Entry 1 (Segment 1) Destination IP Address Network Mask (Standard Class C) Gateway IP Address (ADE-4300/ADW-4300's l l R t ) 114

122 Chapter 8 Modem Mode 8 This Chapter explains configuration and operation when in "Modem" or "Bridge" mode.. Overview There are two modes available on the Mode screen. Router - Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related information to all Wireless (ADW-4300 only) and LAN users. Modem - Only the ADSL Modem component is operational. All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point (ADW-4300 only). This Chapter describes operation while in Modem Mode, also called Bridge Mode. Management Connections When this device restarts in Modem mode, the IP address does not change, but the DHCP server is disabled. However, your PC will usually retain the IP address provided by the DHCP Server, so the connection will be automatically re-established. You then need to ensure that the IP address of this modem is suitable for your LAN. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point (ADW-4300 only). This Modem/AP (ADW-4300 only) must be a valid device on your LAN, to allow management connections. You must assign a (fixed) IP address which is within the address range used on your LAN, but not within the address range used by your DHCP server. When you connect in future, just connect normally, using the IP address you assigned. 1. Start your WEB browser. 6 In the Address box, enter " and the current IP Address of the ADE- 4300/ADW-4300, as in this example, which uses the ADE-4300/ADW-4300's default IP Address: 7 When prompted for the User name and Password, enter admin for the user name, and the current password, as set on the password screen.

127 Appendix A Troubleshooting A This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the ADE-4300/ADW-4300 and some possible solutions to them. If you follow the suggested steps and the ADE-4300/ADW-4300 still does not function properly, contact your dealer for further advice. General Problems Problem 1: Solution 1: Can't connect to the ADE-4300/ADW-4300 to configure it. Check the following: The ADE-4300/ADW-4300 is properly installed, LAN connections are OK, and it is powered ON. Ensure that your PC and the ADE-4300/ADW-4300 are on the same network segment. (If you don't have a router, this must be the case.) If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range to and thus compatible with the ADE-4300/ADW-4300's default IP Address of Also, the Network Mask should be set to to match the ADE-4300/ADW In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. Internet Access Problem 1: Solution 1: When I enter a URL or IP address I get a time out error. A number of things could be causing this. Try the following troubleshooting steps. Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. If the PCs are configured correctly, but still not working, check the ADE-4300/ADW Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.) 122

128 Appendix A - Troubleshooting Check the ADE-4300/ADW-4300's status screen to see if it is working correctly. Problem 2: Solution 2: Some applications do not run properly when using the ADE- 4300/ADW The ADE-4300/ADW-4300 processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic. You can also use the DMZ function. This should work with almost every application, but: It is a security risk, since the firewall is disabled. Only one (1) PC can use this feature. Wireless Access (ADW-4300 only) Problem 1: Solution 1: Problem 2: Solution 2: My PC can't locate the Wireless Access Point. Check the following. Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode) The SSID on your PC and the Wireless Access Point are the same. Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup". Both your PC and the ADW-4300 must have the same setting for WEP. The default setting for the ADW-4300 is disabled, so your wireless station should also have WEP disabled. If WEP is enabled on the ADW-4300, your PC must have WEP enabled, and the key must match. If the ADW-4300's Wireless screen is set to Allow Trusted PCs only, then each of your Wireless stations must have been designated as "Trusted", or the Wireless station will be blocked. To see if radio interference is causing a problem, see if connection is possible when close to the ADW Remember that the connection range can be as little as 100 feet in poor environments. Wireless connection speed is very slow. The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following: ADW-4300 location. Try adjusting the location and orientation of the ADW Wireless Channel If interference is the problem, changing to another channel may show a marked improvement. Radio Interference Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" 123

129 ADE-4300/ADW-4300 User Guide devices should be shielded or relocated. RF Shielding Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the ADW

130 Appendix B About Wireless LANs(ADW-4300 only) B This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: Ad-hoc Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best 125

131 ADE-4300/ADW-4300 User Guide performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) Channels The Wireless Channel sets the radio frequency used for communication. Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WEP Key WEP Authentication Off, 64 Bit, 128 Bit For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match Open System or Shared Key. WPA-PSK WPA-PSK is another standard for encrypting data before it is transmitted. This is a later standard than WEP (Wired Equivalent Privacy), and provides greater security for your data. Data is encrypted using a 256Bit key which is automatically generated and changed often. If all your Wireless stations support WPA-PSK, you should use this instead of WEP. If WPA-PSK is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WPA PSK (Pre-shared Key) Enter the same value on every station and the AP. The PSK must be from 8 to 63 characters in length. The 256Bit key used for the actual encryption is derived from this key. 126

132 Appendix B - About Wireless LANs Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widelysupported method is AES. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode SSID (ESSID) Wireless Security On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to "any" or null (blank) to allow connection to any Access Point. The Wireless Stations and the Access Point must use the same settings for Wireless security. (None, WEP, WPA-PSK). WEP: If WEP is used, the Key size (64Bit, 128Bit), Key value, and Authentication settings must be the same on the Wireless Stations and the Access Point. WPA-PSK: If WPA-PSK is used, all Wireless Stations must be set to use WPA-PSK, and have the same Pre-shared Key and encryption system. For Ad-hoc networks (no Access Point), all Wireless stations must use the same security settings. 127

133 Appendix C About VPNs C Overview A VPN (Virtual Private Network) provides a secure connection between 2 points, over an insecure network - typically the Internet. This secure connection is called a VPN Tunnel. There are many standards and protocols for VPNs. The standard implemented in the ADE-4300/ADW-4300 is IPSec. IPSec IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It works at the packet level, and authenticates and encrypts all packets traveling over the VPN Tunnel. Thus, it does not matter what applications are used on your PC. Any application can use the VPN like any other network connection. IPsec VPNs exchange information through logical connections called SAs (Security Associations). An SA is simply a definition of the protocols, algorithms and keys used between the two VPN devices (endpoints). Each IPsec VPN has two SAs - one in each direction. If IKE (Internet Key Exchange) is used to generate and exchange keys, there are also SA's for the IKE connection as well as the IPsec connection. There are two security modes possible with IPSec: Transport Mode - the payload (data) part of the packet is encapsulated through encryption but the IP header remains in the clear (unchanged). The ADE-4300/ADW-4300 does NOT support Transport Mode. Tunnel Mode - everything is encapsulated, including the original IP header, and a new IP header is generated. Only the new header in the clear (i.e. not protected). This system provides enhanced security. IKE The ADE-4300/ADW-4300 always uses Tunnel Mode. IKE (Internet Key Exchange) is an optional, but widely used, component of IPsec. IKE provides a method of negotiating and generating the keys and IDs required by IPSec. If using IKE, only a single key is required to be provided during configuration. Also, IKE supports using Certificates (provided by CAs - Certification Authorities) to authenticate the identify of the remote user or gateway. If IKE is NOT used, then all keys and IDs (SPIs) must be entered manually, and Certificates can NOT be used. This is called a "Manual Key Exchange". When using IKE, there are 2 phases to creating the VPN tunnel: Phase I is the negotiation and establishment up of the IKE connection. Phase II is the negotiation and establishment up of the IPsec connection. 128

134 Appendix C - VPNs Because the IKE and IPsec connections are separate, they have different SAs (security associations). Policies VPN configuration settings are stored in Policies. Note that different vendors use different terms. Generally, the terms "VPN Policy", "IPSec Policy", and "IPSec Proposal" have the same meaning. However, some vendors separate IKE Policies (Phase 1 parameters) from IPSec Policies (Phase 2 parameters). For the ADE-4300/ADW-4300; each VPN policy contains both Phase 1 and Phase 2 parameters (if IKE is used). Each policy defines: The address of the remote VPN endpoint The traffic which is allowed to use the VPN connection. The parameters (settings) for the IPsec SA (Security Association) If IKE is used, the parameters (settings) for the IKE SA (Security Association) Generally, you will need at least one (1) VPN Policy for each remote site for which you wish to establish VPN connections. It is possible, and sometimes necessary, to have multiple Policies for the same remote site. However, you should only Enable one (1) policy at a time. VPN Configuration The general rule is that each endpoint must have matching Policies, as follows: VPN Endpoint address Local & Remote LAN definition IKE parameters IPsec parameters Each VPN endpoint must be configured to initiate or accept connections to the remote VPN client or Gateway. Usually, this requires having a fixed Internet IP address. However, it is possible for a VPN Gateway to accept incoming connections from a remote client where the client's IP address is not known in advance. This determines which outgoing traffic will cause a VPN connection to be established, and which incoming traffic will be accepted. Each endpoint must be configured to pass and accept the desired traffic from the remote endpoint. If connecting 2 LANs, this requires that: Each endpoint must be aware of the IP addresses used on the other endpoint. The 2 LANs MUST use different IP address ranges. If using IKE (recommended), the IKE parameters must match (except for the SA lifetime, which can be different). The IPsec parameters at each endpoint must match. 129

135 ADE-4300/ADW-4300 User Guide Common VPN Situations VPN Pass-through Figure 96: VPN Pass-through Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connection. The PC software can use any VPN protocol supported by the remote VPN. The remote VPN Server must support client PCs which are behind a NAT router, and so have an IP address which is not valid on the Internet. The Router/Gateway requires no VPN configuration, since it is not acting as a VPN endpoint. Client PC to VPN Gateway Figure 97: Client PC to VPN Server In this situation, the PC must run appropriate VPN client software in order to connect, via the Internet, to the ADE-4300/ADW-4300 or other VPN Gateway. Once connected, the client PC has the same access to LAN resources as PCs on the local LAN (unless restricted by the network administrator). IPsec is not the only protocol which can be used in this situation, but the ADE- 4300/ADW-4300 supports IPsec ONLY. Windows 2000 and Windows XP include an IPsec VPN client program. However, configuration of this client program for use with the ADE-4300/ADW-4300 is very complex and beyond the scope of this document. 130
